Design drawing of a narrow and long sunken courtyard

Quick answer：

A sunken courtyard design typically features a courtyard that is lower in elevation than the surrounding ground level. This design creates a sense of privacy and seclusion, often used in traditional Chinese gardens. The narrow and long dimensions suggest a deliberate layout to maximize space while maintaining a serene atmosphere. The design would include elements such as steps, water features, plants, and possibly structures like pergolas or pavilions to enhance the visual and functional aspects of the space.
